Crosswind kite power is power derived from airborne wind-energy conversion systems (AWECS, also AWES) or crosswind kite power systems (CWKPS). The kite system is characterized by energy-harvesting parts flying transversely to the direction of the ambient wind, i.e., to crosswind mode; sometimes the entire wing set and tether set are flown in crosswind mode.
Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack ...
Upwind: the rotor harvests power from the oncoming air and drives the wheels, as would a wind turbine. Downwind: when the vehicle is traveling faster than the windspeed, the ground is the fastest-moving medium relative to the vehicle, so the wheels harvest the power and impart it to the rotor, which propels the vehicle.

When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine. If the height of a rooftop mounted turbine tower is approximately 50% of the building height it is near the optimum for maximum wind energy and minimum wind turbulence.
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
The son of the car's owner told ABC affiliate KABC Friday that the account was misinterpreting a Tagalog word on the license plate. The son, who the station did not identify, said that the plate ...
Amos was charged with possession of a controlled substance, DUI and reckless driving, according to WSLS. The cause of death was hanging, using a bedsheet. He was reportedly in medical segregation because of injuries from a car accident. Jail or Agency: New River Valley Regional Jail; State: Virginia; Date arrested or booked: 5/14/2016; Date of ...
The wind pushes each blade around on both the windward and leeward sides of the turbine. The qr5 turbine, rated for 6.5 kW, measures 3.1 metres (10 feet) in diameter [5] and 5.5 metres (18 feet) high. [6] The qr6 is similar: 3.1 m wide and 6 metres (20 feet) tall and is rated 7.5 kW. [7]
